The perimeter and everything inside it
Network Security Services
Your network carries everything the business does: payments, payroll, client files, the boss's email. Network security is the ongoing work of making sure it carries them only to the people it should.
What our network security services cover
The perimeter first: firewalls configured, monitored and actually updated, VPN access that does not date from 2019, and intrusion detection watching what crosses the boundary. Then the inside, which most breaches now travel through: network segmentation so a compromised front-desk PC cannot reach the accounting server, wireless done properly with guest traffic walled off, and switch-level controls that stop a stranger in the lobby from plugging in and joining the company.
Then the unglamorous discipline that decides outcomes: firmware kept current on every device that moves a packet, configurations backed up and reviewed, and change logs that can answer who opened that port and when. Every change lands in the log, every device lands in the inventory, and both are yours to read.
Built to a framework, not a feeling
Our network security services are measured against published guidance rather than vibes, chiefly CISA's Cyber Essentials and the relevant CIS controls. That matters for two audiences. Auditors and insurers get answers in a language they already accept. And you get findings ranked by consequence, so the budget goes to the gap an attacker would actually use, not the one that happens to be fashionable. The framework language also shortens insurance questionnaires from an afternoon to a coffee.
Signs your network needs attention
The wifi password has not changed since the office opened. Ex-employees could still be on the VPN, and nobody is certain either way. The firewall was installed by a vendor no longer in business. Guests join the same network as the file server. Any one of these is common. All four together is an invitation, and we see all four together weekly. If any of them sounds familiar, network security services are overdue, and the review will tell you how overdue. The review is quick, the findings are written in plain English, and nothing in it obligates you to buy anything.
How the engagement runs
It starts with a review, not a proposal. We map what you actually have: every firewall, switch, access point and VPN endpoint, what firmware it runs, and who can log into it. The map alone usually surfaces surprises, the forgotten access point above the ceiling tiles, the firewall rule opened for a vendor in 2022 and never closed. We also check the quiet dependencies: which systems assume the network is flat, which vendors hold standing remote access, and what would actually happen if the primary firewall died on a Friday.
From there, network security services run as a cycle rather than a project. Dangerous findings get fixed first, monitoring goes onto what remains, and reviews recur on a schedule so the network you secured in January is still the network you have in June. Pricing follows the size of the estate, the number of sites and devices under management, and most clients fold it into their managed services agreement with a quarterly report that proves the work happened. No scare slides, just the list and the order to fix it in.
How it fits the rest of the stack
Network security is the ground floor. Managed firewall service runs the perimeter day to day, managed detection and response watches for what slips past it, and a penetration test proves the whole arrangement against a live adversary. Start with the review; it tells you which of those you need first.
